Tiny microphones almost invisible to the naked eye are being knitted into the fabric covering army helmets to reduce the risk of soldiers developing hearing injuries, thanks to new research by Nottingham Trent University.
The microphones – when knitted into the fabric covering regular personnel headwear – will be undetectable to the user and avoid interfering with military activities. “This innovation will dramatically reduce the risk of service personnel injured due to long-term noise exposure,” said Professor Dias.
“By integrating a low-cost and discrete dosemeter directly into a textile, such as a helmet cover, the noise exposure of personnel will be monitored and stored, providing the data necessary to take preventative action in the future.
